MDMA use before surgery

I have a friend that will be undergoing general anesthesia in a week for a procedure. They were wondering if taking a single dose of 130mg MDMA (it’s been tested) in a couple of days would have any adverse effects on them in regards to the anesthesia. I would rather them be safe than sorry so any information would be helpful.

It is unlikely that taking MDMA 48 hours before anaesthesia can produce severe, life threatening effects. But psychological negative after effects of MDMA tipically appears 48 hours after using it, and a surgical intervention is not, in general, a pleasant experience. I would recommend waiting for a better moment
